from Ted's televised statement to the nation on 7 - 25 - 69:
On the weekend of July 18th, I was on Martha's Vinyard Island participating with my nephew, Joe Kennedy, as for 30 years my family has participated in the annual Edgartown Sailing Regatta. Only reasons of health prevented my wife from accompanying me.
On Chappaquiddick Island off Martha's Vinyars, I attended on Friday evening, July 18th, a cookout I had encouraged and helped sponsor for a devoted group of Kennedy campaign secretaries. When I left the party around 11:15 PM, I was accompanied by one of these girls, Miss Mary Jo Kopechne. Mary Jo was one of the most devoted members of the staff of Senator Robert Kennedy. She worked for him for four years and was broken up over his death. For this reason and because she was such a gentle, kind and idealistic person, all of us tried to help her feel that she still had a home with the Kennedy family.
